摘要目的 探讨产时胎儿电子监护(electronic fetal monitoring,EFM)图形的数学特征与新生儿酸中毒的关系,以辅助临床评估“不确定”型EFM图形的临床意义. 方法 回顾性纳入2011年2月4日至12月5日在北京大学第三医院产科自然分娩或产程中转剖宫产的产妇共85例,取分娩前0.5~1 h的EFM图,提取数据点,分析其数学特征,包括胎心基线率、单位时间减速区面积(cm2/min)、减速持续时间比例、单位时间轻中度及重度变异减速的个数.根据分娩后脐动脉血气结果分为酸中毒(n=12)及非酸中毒组(n=73),采用两独立样本t检验和非参数秩和检验比较组间FEM图形的数学特征的差异. 结果 酸中毒组减速持续时间比例及单位时间减速区面积分别为0.56±0.17和0.45 cm2/min (0.38~0.79 cm2/min),高于非酸中毒组[分别为0.42±0.14和0.30 cm2/min (0.19~0.41 cm2/min)],差异均有统计学意义(t=2.889,Z=2.587,P均<0.05).酸中毒组单位时间轻中度及重度变异减速的个数分别为(0.44±0.14)个/min和0.033个/min(0.016~0.062个/min),与非酸中毒组[分别为(0.41±0.13)个/min和0.016个/min(0.008~0.033个/min)]比较,差异没有统计学意义(t=1.318,Z=-1.596,P均>0.05). 结论 产时EFM图形中减速持续时间比例及单位时间减速区面积有助于辅助产程中EFM图形的解读. Objective To explore the relationship between mathematical characteristics of cardiotocograph in electronic fetal monitoring (EFM) and umbilical blood acidosis,and help to evaluate the clinical significance of "indeterminate" EFM.Methods A total of 85 vaginal delivery cases (or transfer to caesarean section during labor) hospitalized in Peking University Third Hospital during February 4 to December 5,2011 was enrolled in this retrospective study.EFM monitored 0.5-1 hour before delivery was recorded and the mathematical characteristics as the baseline,deceleration area per unit time (cm2/min),deceleration duration ratio and some other variables of EFM were analyzed.All cases were divided into acidosis (n=12) and non-acidosis group (n=73) based on the umbilical blood gas results.Rank sum test or t-test were used to compare the difference on mathematical characteristics between these two groups.Results The deceleration duration ratio and deceleration area per unit time in acidosis group were 0.56±0.17 and 0.45 cm2/min (0.38-0.79 cm2/min),which were higher than those in non acidosis group [0.42±0.14 and 0.30 cm2/min (0.19-0.40 cm2/min)],the differences were statistically significant (t=2.889,Z=2.587,both P<0.05).There were no statistically significant differences in the number of mild variable deceleration and severe deceleration per unit time between acidosis group and non acidosis group [(0.44± 0.14)/min vs (0.41±0.13)/min,t=1.318,P>0.05; 0.033/min (0.016-0.062/min) vs 0.016/min (0.008-0.033/min),Z=-1.596,P>0.05].Conclusions The deceleration duration ratio and deceleration area per unit time can be used to assist the interpretation of "indeterminate" EFM.
